IMPROVED SPRING BED-BOTTOM.

Speeilieation forming part of Letters Patent No. 30,635, dated November 13, 1860.

To @ZZ whom, t may con/cerne:

Beit known that we, MEIER RosENBEnG and HENRI SCHEERLE, both of New York, in the eounty and State of New York, have 'invented a new and useful Improvement in Spring Bed-Bottoms; and we hereby declare that the following is a lull and exact deseription of the same, reference being had to the accompanying drawings, and to the letters oi' reference marked thereon.

Figure I represents a top view, and Fig. Il a longitudinal seetion, ot' our spring-bottoni.

On the side rails, a a., of the bedstead we attaeli side pieces, n n, running the whole length ofthe bed, and which support spiral springs d d, on the top of which said springs the bedbottom B rests. rEhe springs d may be let in some, distance into the side pieces, a a, as well as into the under side of the bedbottom B. By this arrangement the bed-bottom is supported on both sides on springs, giving thereby the same the neeessary elasticity. Instead oi' spiral springs, elliptie springs may be used. rllle four corners oi" the bed-bottom B are connected to t-he side pieces, a, by means ot hinges m m, and so constructed that said hinges allow the bed-bottom toloe pressed downward as mueli as the strength of the springs d will allow, or until stopped by the side pieces, n, while projections 2 and 3, provided ou the hinges, will prevent the openings of said hinges farther than desired, and consequently prevent the spring bed-bottom from moving higher upward than intended. By this arrangement itis impossible that the springs can get out of their proper places, as is often the ease whenever a weight is brought suddenly upon one side or end of the bed-bottom, by which the opposite side or end is suddenly thrown upward, and causing adisarrangement ofthe springs, while with our arrangement the bed-bottom, although at perfect liberty to move downward until stopped bythe strength of the springs or the side pieces, is by means of t-hese hinges prevented from being pressed up at any point higher than desired, and consequently every disarrangement prevented.

7e are aware that bed-bottoms have been supported on springs at the sides and ends, and consequently do not claim this as new; but

Vha-t we Claim as our invention, and desire to secure by Letters Patent, is-

The arrangement and combination of hinges with a bed-bottom supported by springs, in the manner and for the purpose substantially as described.
